The Black-tailed dasyure is native to
New Guinea, where it ranges across the
Central Cordillera of
Western New Guinea, which is part of
Indonesia, and of
Papua New Guinea. It is also present in the
Arfak Mountains of Western New Guinea and the
Torricelli Mountains in northern Papua New Guinea. It is found from sea level to mid-montane areas up to 2,800 meters elevation. Its natural habitat is forest, including lowland rain forest and montane rain forest (mid-montane forest, beech forest, pandanus forest, and mossy forest). It is fairly abundant across its range, and its population is stable. ==Breeding==
